Abstract
Description
Technical Field
[0001] This utility model belongs to the field of battery cell processing technology, and in particular relates to a battery stacking material handling device. Background Technology
[0002] In the manufacturing process of lithium batteries, lithium battery cells manufactured using the lamination process are formed by separating and stacking positive and negative electrode sheets using a separator. However, the electrode lamination process is often carried out manually or by manual machinery. This process involves too many human interference factors, unstable product quality, and difficulties in environmental control. Not only does it fail to meet the required precision, but it also results in a low product yield, increased costs, and makes large-scale mass production impossible.
[0003] To overcome the aforementioned technical deficiencies, Chinese patent document CN210430010U discloses a lithium battery stacking device, including a working platform and an electrode supply mechanism, a separator unwinding mechanism, a stacking table mechanism, a cell stretching mechanism, and a cell adhesive application mechanism located above the working platform; the stacking table mechanism is located at the end of the electrode supply mechanism, which is used to transfer positive and negative electrode sheets one by one onto the stacking table mechanism; the separator unwinding mechanism is located above the stacking table mechanism. The stacking stage provides the separator required for stacking, and stacks the positive electrode, negative electrode, and separator to form a battery cell. A cell stretching mechanism is located on one side of the stacking stage, used to remove the battery cell from the stacking stage and cut the separator. A cell adhesive applicator is located on one side of the cell stretching mechanism, with a robotic arm above it to transfer the battery cell to the adhesive applicator for applying adhesive. This lithium battery stacking equipment can sequentially automate electrode feeding, separator supply, stacking, cell adhesive application, and cell unloading. The entire process is fully automated, requiring no human intervention, thus improving automation, stacking efficiency, and overall production efficiency while reducing labor intensity. Furthermore, it enables electrode positioning, ensuring precise electrode placement before stacking and improving equipment accuracy.
[0004] The technical solution disclosed in the aforementioned patent document involves a robotic arm positioned above the battery cell winding mechanism and the battery cell adhesive application mechanism. This robotic arm transfers the battery cells from the winding mechanism to the adhesive application mechanism, which then applies adhesive to the cells. However, in this solution, the robotic arm, stacking table, and electrode supply mechanism are all independently mounted on the worktable, thus increasing the overall size and space required.

[0005] The purpose of this utility model is to provide a battery stacking material handling device to solve the problem that the various mechanisms of the existing automated stacking machine occupy the space of the machine independently, resulting in a large machine size.

[0010] Furthermore, the clamping assembly includes a drive member and two grippers; the drive member is located at the moving end of the cross translation mechanism, and the drive member includes two relatively movable slides, with the two grippers respectively located on the two slides; the grippers include a plurality of spaced-apart teeth.

[0014] The battery stacking and feeding device of this utility model has the following beneficial effects:
[0015] The machine is equipped with a stacking table, an electrode positioning mechanism, and a picking mechanism. Electrodes are first positioned on the positioning table of the electrode positioning mechanism, then repositioned by the positioning table before being stacked onto the stacking table, thus completing the cell stacking. After stacking, the picking mechanism removes the cells from the stacking table. Specifically, when removing the cells from the stacking table, a lifting mechanism drives the positioning table to descend until it is flush with the top surface of the machine. Then, a cross-shaped translation mechanism drives the clamping assembly to move above the positioning table to the stacking table position to remove the cells. Because the positioning table of the electrode positioning mechanism descends to avoid the picking mechanism, the overall structure can be more compactly arranged on the machine, reducing the overall size and lowering equipment costs.

[0023] The following detailed embodiments will be further explained in conjunction with the above-mentioned accompanying drawings.
[0024] Several specific details are set forth below to provide a thorough understanding of the concepts underlying the described embodiments. However, it will be apparent to those skilled in the art that the described embodiments can be practiced without some or all of these specific details. In other instances, well-known processing steps are not specifically described.
[0025] Reference Figure 1 and Figure 2 In one embodiment of the battery stacking and feeding device of this utility model, please refer to Figures 1 to 6 A battery stacking and material handling device includes a machine base 100, a stacking worktable 200, an electrode sheet positioning mechanism 300, and a material handling mechanism 400. The stacking worktable 200, the electrode sheet positioning mechanism 300, and the material handling mechanism 400 are disposed on the machine base 100.
[0026] Reference Figure 5 The stacking worktable 200 is used for stacking battery cells. The electrode sheet positioning mechanism 300 is used to transfer the electrode sheets to the stacking worktable 200 after secondary positioning. The electrode sheet positioning mechanism 300 includes a lifting mechanism 310 and a positioning platform 320. The lifting mechanism 310 is located inside the machine base 100 and includes a lifting end 301 extending from the top surface of the machine base 100. The positioning platform 320 is located at the lifting end 301.
[0027] Reference Figure 6 The material handling mechanism 400 includes a cross translation mechanism 410 and a clamping assembly 420; the cross translation mechanism 410 is disposed on the machine base 100, and the clamping assembly 420 is disposed on the moving end of the cross translation mechanism 410; a portion of the path through which the cross translation mechanism 410 drives the positioning table 320 to move overlaps with the position of the positioning table 320.
[0028] Please refer to Figures 1 to 3In this embodiment, the electrode sheet can be first positioned on the positioning platform 320 of the electrode sheet positioning mechanism 300. After the positioning platform 320 performs secondary positioning on the electrode sheet, it is stacked on the stacking worktable 200 to complete the cell stacking. After the cell stacking is completed, the picking mechanism 400 removes the cell from the stacking worktable 200. Specifically, when removing the cell from the stacking worktable 200, the lifting mechanism 310 drives the positioning platform 320 to descend to be in contact with the top surface of the machine base 100, and then the cross translation mechanism 410 drives the clamping assembly 420 to move over the positioning platform 320 to the position of the stacking worktable 200 to remove the cell from the stacking worktable. Since the positioning platform 320 of the electrode sheet positioning mechanism 300 descends to avoid the picking mechanism 400, the overall structure can be set more compactly on the machine base, reducing the overall volume and lowering the equipment cost.
[0029] Furthermore, refer to Figure 6 The cross-shaped translation mechanism 410 includes a first translation mechanism 411, a moving plate 412, a second translation mechanism 413, and a moving base 414.

The second translation mechanism 413 is mounted on the moving plate 412 and is perpendicular to the first translation mechanism 411. The moving base 414 is mounted on the second translation mechanism 413, and the clamping assembly 420 is mounted on the moving base 414. Specifically, the first translation mechanism 411 drives the moving plate 412 to the top of the positioning table 320, and then the second translation mechanism 413 drives the clamping assembly 420 on the moving base 414 to move to the top side of the stacking worktable 200 to clamp the battery cell. The first translation mechanism 411 and the second translation mechanism 413 are both electric linear modules, which can be belt driven or screw and nut driven structures.

The driving member 421 is located at the moving end of the cross translation mechanism 410, and includes two relatively movable slides 423. The two grippers 422 are respectively disposed on the two slides 423. Each gripper 422 includes a plurality of spaced-apart teeth 424. In this embodiment, the driving member 421 drives the two slides 423 to move towards each other, so that the two grippers 422 clamp the battery cell. Specifically, the driving member 421 is a bidirectional cylinder, or a screw mechanism with left-hand and right-hand threads. Furthermore, the stacking worktable 200 is also provided with clearance grooves for the grippers 422. When the grippers 422 extend towards the stacking worktable 200, the grippers are located in the clearance grooves, thereby allowing the battery to be clamped.
[0031] Furthermore, refer to Figure 6 The clamping assembly 400 further includes a translation cylinder 430, which is located at the moving end of the cross translation mechanism 410. The translation cylinder 430 has a connecting seat 431, and the driving member 421 is located on the connecting seat 431. The translation cylinder 430 increases the travel distance of the clamping assembly 400.
[0032] Furthermore, refer to Figure 5 The lifting mechanism 310 includes an electric slide 311, a lifting plate 312, and support rods 313. The electric slide 311 is located on the bottom side of the machine base 100, the lifting plate 312 is connected to the electric slide 311, multiple support rods 313 are mounted on the lifting plate 312, the support rods 313 pass through the top plate of the machine base 100, and the positioning platform 320 is located at the top of the support rods 313. In this embodiment, the electric slide 311 drives the lifting plate 312 to rise and fall, thereby driving the support rods 313 and the positioning platform 320 on the support rods 313 to rise and fall.
[0033] Furthermore, refer to Figure 5 The positioning platform 320 includes a base plate 321, a pad 322, and positioning blocks 323. The base plate 321 is located at the lifting end 301 of the lifting mechanism 310, the pad 322 is located on the base plate 321, and the positioning blocks 323 are provided on the four sides of the pad 322. Each positioning block 323 surrounds a positioning cavity, and a guide angle 324 is provided on the side of the positioning block 323 closest to the positioning cavity.
